I feel it is racist and presumptuous for a bunch of ugly Americans to sully Patrick's good name by doing nothing but wear gaudy trash and get rip-roaring drunk. It's disrespectful to actual Irish people. It is a level of parody and mockery that would be met with violence if it were used against a protected class such as Blacks or LGBT.
I am, in fact, a teetotaler, and I belong to an Irish association that promotes temperance and we practice total abstinence from intoxicating drinks. I took inspiration from my pastor, who was a member and spoke of his experience. It is not a great sacrifice for me to give up alcohol, but it was a pleasure to drink sometimes, and so I offer it up for those who can't stop. Every time I see a drinker on the street, or an abandoned Steel Reserve at a bus stop, I stop and recite our pledge-prayer for them.
I feel that drunkenness and intoxication ruins lives and steals innocence. I believe that marijuana can be useful and has a place in society, but I also believe that it can be abused, and I don't much enjoy being exposed to a constant flow of secondhand smoke of any kind (my downstairs neighbor seemed to have a regular pot habit, and so my bedroom would fill daily with smoke, and I'm sure I had a contact high. This interacts poorly with my meds.)
Drunk drivers ruin holidays for many people. I try to stay off the roads, as a pedestrian, during peak-drunk seasons. A girlfriend once insisted it was perfectly safe to drive while stoned. I'm not so sure.
